a client needs archivable videos and subtitles, but don’t know what formats they want
We just finished a large project, and the client, a textbook publisher, wants to archive “uncompressed layered video files, but we haven’t defined a format for that yet.”
They’re not video editors. When they say “uncompressed layered video,” I assume they’re thinking of Photoshop files and assuming there’s an equivalent in video terms, but I’m not sure.
The bottom line is that they need to check off a form on their end that says they have digital masters of the DVD series that they can reuse and potentially re-edit in minor ways in the future. So we thought about giving them ProRes files, and letting them convert as needed years down the road. But the videos are actually delivered on DVD with subtitles. Should we send them the .stl files that went into the DVD? Should we give them the DVD masters (.iso) and ProRes, or something else?
I know the real answer is to wait until they know what they need, but for reasons I won’t explain here, we can’t wait. It’s also not clear that we could ever get a clear answer, because they’re looking to us for guidance, which is reasonable. So what’s a good package of files to send to them? What would you do in this case?
